Different Electric Vehicle Charging Strategies to avoid Reducing the Insulation Oil Lifetime of Distribution Transformers

Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...

Optimization Methods to Plan the Charging of Electric Vehicle Fleets

This paper describes an approach to optimize electric vehicle battery charging behavior with the goal of minimizing charging costs, achieving satisfactory state-of-energy levels, and optimal power balancing. Two methods for charging schedule optimization are compared. The first formulation uses a linear approximation of the battery behavior, whereas the second uses a quadratic approximation. A ...

Demand Prediction and Placement Optimization for Electric Vehicle Charging Stations

Due to the environmental impact of fossil fuels and high variability in their prices, there is rising interest in adopting electric vehicles (EVs) by both individuals and governments. Despite the advances in vehicle efficiency and battery capacity, a key hurdle is the inherent interdependence between EV adoption and charging station deployment–EV adoption (and hence, charging demand) increases ...
